Patent GB-1338743-A (GB)
Title: Meter prover apparatus and method
IPC: G01F25/00
Filed: 1972-07-06
Abstract: 1338743 Meter proving device M H GROVE and J M E GROVE [trading as M & J DEVELOPMENT CO] 6 July 1972 [28 July 1971 27 Sept 1971] 31819/72 Heading G1B A tight fitting sphere 1 or 2 is propelled through a metering tube having an inlet 9a and an outlet 9b by the flow to be measured and the time taken for the sphere to pass from detector 10 to detector 11 measured, the spheres being collected from outlet 9b and injected into inlet 9a by an interchange 13. The interchange includes a sleeve 15 in which the spheres are a tight fit, a plunger 23 having a pair of opposed cup shaped seals 27, 28 Fig.7 for forming a seal with the sleeve and a guard 63 slidable along the rod 22 mounting the plunger 23 and resting on a stop 64 when the plunger is within the sleeve. The liquid to be metered enters at T-piece 20 and exits at T-piece 12 through pipe 18. A by-pass 21 connects the T-piece 14 with pipe 18. From the position shown in Fig.1, the plunger 23 is moved downwardly by means of hydraulic ram 24 Fig.4 to inject sphere 1 into the flow, and the sphere is carried around the metering tube and emerges from outlet 9b into T-piece 12. Ribs 19 guide the sphere 1 along T-piece 12 so that it abuts guard 63, a vertical rib 19a pushing the sphere off centre to prevent it being held stationary over pipe 18 by the liquid flow. The plunger is then raised to the top of the T-piece 14 by hydraulic ram 24, the guard 63 being lifted upwardly by the plunger. Sphere 2 rises with the plunger until the seal with sleeve 15 is broken, and when the guard moves upwardly sphere 1 rolls on to sphere 2. Downward movement of plunger 23 then reproduces the arrangement of Fig.1 with the positions of spheres 1 and 2 interchanged. The seal of the plunger to the sleeve 15 is tested each cycle by a pressure switch 41 connected to the space 33 between the sealing cups 27, 28. As the plunger moves downwardly, a switch 93 is operated to actuate solenoid vent valve 40 for a short time, and then operation of switch 41 indicated leakage into space 33. Leakage past the spheres may also be determined by means of an orifice 57 in sleeve 15 connected to a pressure switch 61 and a solenoid vent valve 58 which may vent to atmosphere or to a higher pressure. The spheres may be removed through a cover 17, and liquid may be passed into sleeve 15 via valve 62 and orifice 57 to aid recovery of the second sphere. The guard 63 may be a tight sliding fit on the plunger rod 22 Fig.8 (not shown) or an alternative pivoting guard arrangement may be used Figs. 9 and 10, (not shown). The T-piece 12 may be sloping Fig. 11 (not shown) or the interchange may be arranged generally horizontally Figs.13 and 14 (not shown). A control circuit Fig.12 (not shown) is described for automatically taking the device through one cycle on actuation of a switch, the beginning and the end of the cycle corresponding to the uppermost portion of the plunger.

Title: Improvements in shock absorbers
IPC: F16F9/14
Filed: 1934-11-06
Abstract: 432,331. Hydraulic shock-absorbers. AKTIEBOLAGET MASTER-REGULATOR, 43, Karlavõgen, and SALENIUS, C. G. T., 13, Tomtebogatan, both in Stockholm. Nov. 6, 1934, No. 31842. [Class 108 (iii)] In an hydraulic shockabsorber wherein, when a shock occurs, liquid is forced by a piston or vane from a pressure chamber to a discharge chamber through two or more discharge channels, the liquid streams issuing from the channels meet each other in a space sufficiently restricted to cause the streams to be damped prior to entering the discharge chamber. The invention is shown applied to a single - acting, rotary - vane, shock - absorber, the controlling device being mounted in a channel 24 in a movable vane or in a fixed partition 13 separating pressure and discharge chambers 21, 22 respectively. Passages 30, 31 are provided in the wall of the channel 24 and connect the chamber 21 through bevelled passages 32, 33 and a channel 55 in a screw-head 28 with an annular space 29 formed between the screw-head 28 and the bottom of a widened portion 26 of the channel 24, the space 29 communicating through radial channels 36 with an axial channel 35 leading to the chamber 22 and controlled by a non-return ball-valve 28. When pressure occurs in the chamber 21 two streams of liquid are forced each through one of the bevelled passages 32, 33 and flow against each other, thus impeding the flow and increasing the resistance. Additional resistance may be obtained by the insertion in the annular space 29 of a temperatureresponsive, resilient, coiled band 39, for example of brass having a thickness of 0'05 to 0À15 mms. and a height of 2 to 3 mms., and a coefficient of expansion greater than that of the surrounding casing. After the two liquid streams meet they pass together between the coils of the band 39 varying the space between the coils and thus the resistance according to the degree of shock. In modifications (a) the band 39 and the walls of the annular space 29 are conical in shape ; (b) the band is in the form of a screw ; (c) a double-acting controlling device is shown which may be replaced by two oppositelyarranged, single-acting devices.

Abstract: 733,446. Colour photography. GRETENER, E. Dec. 19, 1952 [Dec. 22, 1951], No. 32302/52. Class 98 (2). Three colour separation negatives are exposed through a graduated light-control filter or stop and also through a lenticulated raster by light corresponding to the three non-overlapping spectral ranges of a three-emulsion layer highcontrast silver halide material and the latter is processed to produce three dye images in the form of surface elements so that the brightness values of the appertaining separation negatives are recorded in the surface elements of each of the layers by the size of colourless transparent areas relatively to that of uniformly coloured areas, related surface elements of the different layers being disposed one above the other in register so that transparent areas appear within coloured areas or vice versa. Fig. 1 shows the surface elements in separate layers 11, 12, 13 lying on a support 10 and described as of magneta, yellow and cyan (Pu, Ge, Bg) colours respectively; layer 13 comprising elements 14 having transparent areas 15 surrounded by uniformly tinted cyan areas, layer 12 having smaller transparent areas surrounded by yellow areas and layer 11 still smaller transparent areas with, therefore, a nearly continuous magenta base. The brightness or colour intensity of light reflected or transmitted by each separate layer is dependent on the relative sizes of the transparent and coloured areas, thus Fig. 2 showing a single layer with transparent areas 22 on a uniformly tinted background 17 is brightest on the diagonal 20, 20 and least bright, or most deeply coloured, at the corners 19, 21. With superimposition of the surface elements 60, 61, 62 shown at 63, Fig. 6, the transparent area 67 is the size of that of element 61, the adjacent area 66 is the colour of 61, the next area 65 is the colour of 61, 62 in superimposition, and the outside area 64 represents all three colours and, therefore, is black..All other surface elements, as of 14 in Fig. 1 and 63 in Fig. 6, have, similarly, a transparent centre surrounded by a single colour area, then an area which may be of two colours superimposed and then black; the actual colours, the sizes of the colour areas and of the transparent and black areas varying in relation to the actual colours and intensity thereof of corresponding portions of the object or scene represented by the transparency or print. The surface elements are of total area below the resolution of the eye, as 200 Á for prints and 30 Á for colour film. Specification 704,415 is referred to.

Abstract: 1,196,146. Using electric fields to laminate. I. M. RENNIE (International Paper Co.). 13 July, 1967, No. 32310/67. Heading B5N. An extruded film formed from polymers or copolymers of lower olefins and a heated paper substrate are fed along converging paths which meet on a rounded stationary metal surface of a backing bar, and an electric field is created between an electrode and the metal surface, the field acting upon the extruded film to force the latter into bonding contact with the paper substrate. An apparatus for carrying out the process, Fig. 1 (not shown), is similar to that described in Specification 1,196,145, but is provided with an additional set of preliminary rollers which transfer a coating of an adhesion promoter from a trough to the surface of the paper web which will be contacted by the extruded film. The surface of the web not contacted by the film may be cooled in the vicinity of the backing bar. For this purpose, the bar may comprise a hollow tube formed with an axially extending slit in its wall. Coolant introduced into the pipe flows through the slit to form a bead of coolant between the pipe and the part of the web approaching the pipe. A modified electrode structure, Fig. 2 (not shown), includes a tube and a bar, both of aluminium, for concentrating the electric field towards the film.

Abstract: 670,839. Fluid-actuated valves. WAGER, R. H. Dec. 20, 1949 [Oct. 4, 1949], No. 32586/49. Class 135. A valve suitable for use with soot blowers of the kind employing steam at high pressure, e.g. 600 p.s.i., is arranged to permit entry into the blower head of scavenging air when the blower is not working but to close the air inlet when the blower is in operation. The valve comprises a valve member 27 with a grooved stem 28 slidable in a housing 16, 17 and opened by a spring 33 acting on a flange 32. Normally, scavenging air enters at 18 and passes through the valve to the blower head 11, but when the blower is put into operation, steam passing into the valve housing from the blower head closes the valve. The grooves 35 in the stem are such as to prevent too rapid closing movement. A washer 36 placed against the flange 32 adapts the valve for lower steam pressures. In a modification, a spring abutment adjustable on a thread on the part 31 of the valve member is provided.
